' Y sIeivoR To SAID ounnin' I CATTLE smaltoIIIo'ivVV Appl-mamme@December 21,vv ree?. serial Np.'Y 241,'5o4f 1 pivotally mounted neckbars, .provided at their upper ends with arms pivoted thereto and toeach other. common pivot point between the arms, the neck bars are swungrelatively to the head to enlargev or .diminish the space therebetweeninto which the vneck of the animalis to be received. The vinventionfurther pro`V vides a simple mechanism for displacing the abovementioned pivot point y1n the manner desired, and this mechanism'ispreferably,v

controlled by an operating lever.

A The invention is fully disclosed by wayof example in thefollowing'description and 1n the accompanying drawing, .1n which-Vligurel is a front elevation of the devicev in closed position;

F ig. 2 is a section on the line 2-42 of Fig-k ure 1; and

YI4`ig'-3 is a section on the line of vFig-v Lure1.f

Reference to these views will Vnow be madeY by use of like characterswhichV are employed to designate corresponding parts throughout. Thedevice is supported in a frame consist-y ing of a base member 1, a pairof uprights or standards 2 secured thereto, anda pair of rails 3 fixedacross the standards in the same horizontal plane and near the upperends f thereof. A hollow head 4, preferably a metall-ic member, issuspended from the rails by a pair of chains" 5 attached to oppositesides thereof and anchored as at 6 in lthe rails.

Within the hollow member lare pivotally Y vided with chains 27 attachedto rods 28.011

mounted a pair of neck bars 7 in such a manner that the upper endsthereof are free and protrude above' the upper edge of the head 4 asshown in Figure 1.

Several holes 8 are formed through the The operative parts of thepresent device?` include a head supporting a pair of spaced,

The

outer ends of the arms are also provided each with a seriesy ofapertures 14 for selectively receiving the pins 12, whereby the spacingof.

the bars 7 may be further adjusted.

"An arm' 15 has one end pivotally supported betweenthe rails 3 and theother end pro# yby pins 12.'. YThe'arms'll extendinwardly vided with adepending link member 16 which forms aboxor socket 17 'as shown moreclear- L f Y.

ly in Figure 2.- A clip 18 ispivotallyheld'by`v the f'pivot" pin 13ypreviously mentioned and t is equipped with a ball`19 receivedinfthe'socket 17 so thatl aA universal joint isjipro vided between the parts 16and 18.

Theuprights 2 carry clips 20 above fthe; y

rails 3, and in these clips isslidably mounted an .operating rod v21.!`Alink 22 pivoted at both its endsV connects the rod to thenpivot pointbetween the arm 15 and the link memj ber 16. l y- 'Froni .one of ofthelever is attached'asat25 to the `rod21 I the standards2"extends/ai;`bracket'23havi'ng anV operatingllever 24'piv-v` oted,theretointermediateitsends. On'ekend"l 26.l It willbe apparent that by means of theoperatinglever 'the'rod 21 maybe slid across the frame, in consequenceof which the link l. f

member 16 will be raised or lowered according to the direction in whichthe operating lever is swung. This action results in a lifting orlowering of the arms 11 at their common pivot point, so thatthe neckbars 7 will v.

be expanded or contracted beneath the head 4' according tothe directionin which the operation is performed.

VThe lowerL ends of the neck bars are prothe base member 1 for thepurpose of anchor- Ving these yends and yet' permitting movement In theuse of the device, the normal spacing of the bars 7 according to thesize of the animal is determined by adjusting the pins 9 and 12 in theselected apertures 8 and 14. In order to release the animal, or toinitially permit him to enter the device, the operating lever 24: ismoved to the dotted, line position shown in Figure l, whereupon thecommon Vpivot point of the arms l1 is displaced and the bars 7 arecaused to diverge beneath the head 4. In locking the animal betweenthebars, it will be obvious that a reverse movement of the lever 24 willclose the bars on the animals neck. The opening or expanding operationcannot be initiated atlthe bars 7 for the reason. that such movement ofthe bars4 Will tend to lower the common pivot point. of.

thev arms ll, which now decline towards this pivot point, and will causelthe point to bear upon a; heavy.V plate 29 secured on the upper edge ofthe head 4.

Although a speciiic embodiment of the invention has been illustrated anddescribed, it will beunderstood that various alterations in the detailsofV construction. mayv be made without departing from the scope of thein.

vention as indicated by the appended claims.
